Having'thus fully described my invention I ciaim 1. In a headlight, thecombination of a lamp containing casing. an interior therefor comprisingan electric arc lamp and areflector mounted in and on a frame and bywhich frame the reflector is supported at its open end, and meanswhereby the said interior is removablysupportcd within said casing at.the open end of said frame, substantially as described. p

2. In a headlight, the combination of a lamp containing casing, aninterior therefor comprising a'fra'me, a reflector mounted therein andsecured thereto at its open end, and an electric arc lamp carried by theframe, and means whereby the said'structure is removably supported atthe open end of said frame within said casing arounddescribed,disciaimiug, nevertheless, the construction theinnr wallthereof, substantially as described.

In' a headlight, thecombination'of a' lamp containi'ng casing, aninterior therefor consisting of a single structure comprising anelectric arc lamp; :1 reflector having an annular flange around the openend thereot and a frame incasing the reflector and to which the saidannular tiange'is secured,-a supporting frame for said interior-securedaround the innerwall of the casing at the open end thereof, and-meansfor removably said interior within said supporting asdiescribed.

4. In a headlight, a lamp containing casing, an interior thereforcomprising a frame. a reflector havingan anuularflange around its openend and-thereby secured to said frame. and an electric arc lamp frame.in combination ivith means whereby the said frame is supported at theopen end thereof within said casing, substantially as described.
